In which of the following sulphur is present in +5 oxidation state?a)D...
The correct answer is option 'A', dithionic acid. Let's explore each option to understand why.
a) Dithionic acid: Dithionic acid is an inorganic compound with the formula H2S2O6. In this compound, sulfur is present in the +5 oxidation state. Each sulfur atom is bonded to two oxygen atoms and two hydrogen atoms. The oxidation state of sulfur can be determined by assigning oxidation numbers to the atoms in the compound. In dithionic acid, each oxygen atom has an oxidation state of -2 and each hydrogen atom has an oxidation state of +1. Therefore, each sulfur atom must have an oxidation state of +5 to balance the charges.
b) Sulphurous acid: Sulphurous acid is an inorganic compound with the formula H2SO3. In this compound, sulfur is present in the +4 oxidation state. Each sulfur atom is bonded to two oxygen atoms and two hydrogen atoms. Similar to dithionic acid, the oxidation state of sulfur can be determined by assigning oxidation numbers to the atoms in the compound. In sulphurous acid, each oxygen atom has an oxidation state of -2 and each hydrogen atom has an oxidation state of +1. Therefore, each sulfur atom must have an oxidation state of +4 to balance the charges.
c) Sulphuric acid: Sulphuric acid is an inorganic compound with the formula H2SO4. In this compound, sulfur is present in the +6 oxidation state. Each sulfur atom is bonded to four oxygen atoms and two hydrogen atoms. Again, by assigning oxidation numbers to the atoms, we find that each oxygen atom has an oxidation state of -2 and each hydrogen atom has an oxidation state of +1. Therefore, each sulfur atom must have an oxidation state of +6 to balance the charges.
d) Disulphuric acid: Disulphuric acid, also known as pyrosulfuric acid, is an inorganic compound with the formula H2S2O7. In this compound, sulfur is present in the +7 oxidation state. Each sulfur atom is bonded to four oxygen atoms and two hydrogen atoms. By assigning oxidation numbers to the atoms, we find that each oxygen atom has an oxidation state of -2 and each hydrogen atom has an oxidation state of +1. Therefore, each sulfur atom must have an oxidation state of +7 to balance the charges.
In summary, among the given options, dithionic acid (H2S2O6) is the only compound where sulfur is present in the +5 oxidation state.
a) Dithionic acid: Dithionic acid is an inorganic compound with the formula H2S2O6. In this compound, sulfur is present in the +5 oxidation state. Each sulfur atom is bonded to two oxygen atoms and two hydrogen atoms. The oxidation state of sulfur can be determined by assigning oxidation numbers to the atoms in the compound. In dithionic acid, each oxygen atom has an oxidation state of -2 and each hydrogen atom has an oxidation state of +1. Therefore, each sulfur atom must have an oxidation state of +5 to balance the charges.
b) Sulphurous acid: Sulphurous acid is an inorganic compound with the formula H2SO3. In this compound, sulfur is present in the +4 oxidation state. Each sulfur atom is bonded to two oxygen atoms and two hydrogen atoms. Similar to dithionic acid, the oxidation state of sulfur can be determined by assigning oxidation numbers to the atoms in the compound. In sulphurous acid, each oxygen atom has an oxidation state of -2 and each hydrogen atom has an oxidation state of +1. Therefore, each sulfur atom must have an oxidation state of +4 to balance the charges.
c) Sulphuric acid: Sulphuric acid is an inorganic compound with the formula H2SO4. In this compound, sulfur is present in the +6 oxidation state. Each sulfur atom is bonded to four oxygen atoms and two hydrogen atoms. Again, by assigning oxidation numbers to the atoms, we find that each oxygen atom has an oxidation state of -2 and each hydrogen atom has an oxidation state of +1. Therefore, each sulfur atom must have an oxidation state of +6 to balance the charges.
d) Disulphuric acid: Disulphuric acid, also known as pyrosulfuric acid, is an inorganic compound with the formula H2S2O7. In this compound, sulfur is present in the +7 oxidation state. Each sulfur atom is bonded to four oxygen atoms and two hydrogen atoms. By assigning oxidation numbers to the atoms, we find that each oxygen atom has an oxidation state of -2 and each hydrogen atom has an oxidation state of +1. Therefore, each sulfur atom must have an oxidation state of +7 to balance the charges.
In summary, among the given options, dithionic acid (H2S2O6) is the only compound where sulfur is present in the +5 oxidation state.
